A battery has always been a consumable item.
Yes but the way Apple has treated batteries in the past, is not like a part that needs to be replaced during the products life, as they seal it into the device, which means it isn’t treated as a consumable by Apple. A phone shouldn’t need a 150 dollar repair for example after 1-2 years, just to replace the battery, which when worn Apple will slow down the iPhone to prevent it from crashing at 30 percent. So you have to pay for repair, if you want the phone to work properly if you have used it for 1-2 years.
If they have reduced the price of batteries only, does that mean that agents will replace other iPhone batteries for 59 which aren’t covered, eg the 5s which I believe may use the same battery as the se?
